Re-rolled as an Engineer and have been having a blast with it. The Heal Bot is awesome, as it keeps me from having to pop potions all the time. And the flame strike (whatever it's called) is a great way to take out multiple mobs.

I just got to Act II last night, and I'm looking forward to checking out the desert.
